Blood, Physics & the Fine-Tuning Problem | Ep. 1

A Queen Mary University study reveals that electron charge and fundamental physical constants also govern blood viscosity — and life depends on their exact values. The fine-tuning problem just got a second, independent layer.

What's covered

Blood Thickness and Cosmic Constants

If you shifted the charge of the electron by just a few percent, blood would become too thick to flow. That's not a metaphor.

Viscosity as a Life Requirement

Here's what the Queen Mary team found. Liquid viscosity, how easily a fluid flows, turns out to be governed by those same deep physical constants.

Physics-Biology Bridge

A twenty twenty-three follow-up from the same team adds another layer. Liquid viscosity, they argue, isn't just a property you measure in a lab.

Listen now →

What Remains Unproven

The uncertainties are real and worth holding onto. There's no accepted explanation for why the constants have the values they do.

What to Watch Next

The key watchpoint from here is whether independent biochemical modeling firms up those viscosity margins. If the bio-friendly window is confirmed to be genuinely narrow, the case for multiple independent fine-tuning constraints gets significantly stronger.
